> cc1plus: warnings being treated as errors
> Vec.h: In function ‘int main(int, char**)’:
> Vec.h:616: error: assuming signed overflow does not occur when assuming that
> (X + c) < X is always false
> Vec.h:616: error: assuming signed overflow does not occur when assuming that
> (X + c) < X is always false
> Alan says:
> It is a result of optimization in the call sequence in test_append that calls
> str.append(value,len) which calls reserve(length() + count). length() is
> inlined to a reference to n so the argument is treated as "n+count". This
> yields, in the reserve method at the bad line
> if (n+count <= n)
> which leads to the warning/error you see. I don't see how to disable the
> error, though.
